  • Medium Access Control game with an enhanced physical link layer interface
    International Symposium on Information Theory, 2014
    Co-Authors: Yanru Tang, Tiegang Zhao
    Abstract:

    We consider distributed Medium Access Control in a wireless network where each link layer user (transmitter) is equipped with multiple transmission options as opposed to the classical binary options of transmitting/idling. In each time slot, a user randomly chooses a transmission option according to a “transmission probability vector”. Packets sent by the users are either received or lost depending on whether reliable decoding is supported by the communication channel. We propose a game theoretic model for distributed Medium Access Control where each user adapts its transmission probability vector to maximize a utility function. Condition under which the Medium Access Control game has a unique Nash equilibrium is obtained. Simulation results show that, when multiple transmission options are provided, users in a distributed network tend to converge to channel sharing schemes that are consistent with the well-known information theoretic understandings.

  • A Medium Access Control scheme for providing reliability in wireless Ad Hoc networks
    Lecture Notes in Computer Science, 2006
    Co-Authors: Song-hee Lee, Jin-young Choi
    Abstract:

    We propose a Medium Access Control (MAC) protocol called MMPR that supports reliable Medium Access Control in wireless ad hoc networks. MMPR protocol focuses on interaction between a MAC and upper layers, whereby the MAC layer indirectly influences selection of the most reliable next forwarding node set by considering link channel states. The MMPR protocol reduces the number of contention phases and Control frames using transmission power Control techniques, considerably reducing the time required for broadcasting. In addition, our protocol increases throughput under channel fading and interference using a modified CSMA/CA scheme. Our simulation shows that MMPR is substantially more reliable and it provides high throughput in ad hoc network models compared to 802.11 broadcast and BMMM*.

  • Medium Access Control in ultra wideband wireless networks
    IEEE Transactions on Vehicular Technology, 2005
    Co-Authors: Xuemin Shen, Weihua Zhuang, Hai Jiang, Jun Cai
    Abstract:

    Ultra-wideband (UWB) transmission is an emerging wireless communication technology with unique potential merits such as high-rate, low-transmission power, immunity to multipath propagation, and capability in precise positioning. It has received significant interests for future wireless communications from both academia and industry. In UWB wireless networks, Medium Access Control (MAC) is essential to coordinate the channel Access among competing devices. The unique UWB characteristics not only pose significant challenges but also offer great opportunities in efficient UWB MAC design. This paper presents a comprehensive overview of UWB MAC development on four important aspects: multiple Access, overhead reduction, resource allocation, and quality of service (QoS) provisioning, and identifies some future research issues.
